What is this?

This package is a unified (remark) plugin, specifically a remark-lint rule. Lint rules check markdown code style.

When should I use this?

You can use this package to check that autolink literal URLs are not used.

Presets

This rule is included in the following presets:

Preset	Setting
`remark-preset-lint-markdown-style-guide`
`remark-preset-lint-recommended`

Install

This package is ESM only. In Node.js (version 12.20+, 14.14+, or 16.0+), install with npm:

npm install remark-lint-no-literal-urls

In Deno with esm.sh:

import remarkLintNoLiteralUrls from 'https://esm.sh/remark-lint-no-literal-urls@3'

In browsers with esm.sh:

<script type="module">
  import remarkLintNoLiteralUrls from 'https://esm.sh/remark-lint-no-literal-urls@3?bundle'
</script>

Use

On the API:

import {remark} from 'remark'
import remarkLint from 'remark-lint'
import remarkLintNoLiteralUrls from 'remark-lint-no-literal-urls'
import {read} from 'to-vfile'
import {reporter} from 'vfile-reporter'

const file = await read('example.md')

await remark()
  .use(remarkLint)
  .use(remarkLintNoLiteralUrls)
  .process(file)

console.error(reporter(file))

On the CLI:

remark --use remark-lint --use remark-lint-no-literal-urls example.md

On the CLI in a config file (here a package.json):

 …
 "remarkConfig": {
   "plugins": [
     …
     "remark-lint",
+    "remark-lint-no-literal-urls",
     …
   ]
 }
 …

API

This package exports no identifiers. The default export is remarkLintNoLiteralUrls.

`unified().use(remarkLintNoLiteralUrls[, config])`

This rule supports standard configuration that all remark lint rules accept (such as false to turn it off or [1, options] to configure it).

There are no options.

Recommendation

Autolink literal URLs (just a URL) are a feature enabled by GFM. They don’t work everywhere. Due to this, it’s recommended to instead use normal autolinks (<https://url>) or links ([text](url)).

Fix

remark-stringify never creates autolink literals and always uses normal autolinks (<url>).

Examples

`ok.md`

In

<http://foo.bar/baz>

Out

No messages.

`not-ok.md`

In

👉 Note: this example uses GFM (remark-gfm).

http://foo.bar/baz

Out

1:1-1:19: Don’t use literal URLs without angle brackets
